Mazda Halts Rotary Engine Development: Is 2011 Your Last Chance To Wankel?

Though the next-generation of Mazda’s rotary engine has been in development since 2007, and has been the subject of several TTAC Wild-Ass Rumors, WardsAuto reports that the unique engine design could well be reaching the end of its life.

Kiyoshi Fujiwara, Mazda executive officer-product planning and powertrain development, says there is “huge discussion” within the Hiroshima, Japan-based company whether to continue on with a rotary engine.

Fujiwara says economic hardship has some top brass looking for programs to cut, and that the engine program is on the list.

Continuing development of the rotary has been halted for now, but he hopes it will resume in the future, noting the technology is a part of Mazda’s DNA.

Without identifying what exactly they are, Fujiwara says three major problems were identified with the current generation of rotary engine, but that two of the three have been overcome. Still, Mazda says that only one thing will save the rotary engine at this point: success with Mazda’s new suite of SKYACTIV technologies. If these fuel-saving measures spark new interest in the Mazda brand, says Fujiwara, then Mazda might have enough cash to invest in its rotary engine. Alternatively, a Mazda-developed Wankel engine could be used as an electric range-extender. In any case, don’t expect a new Mazda rotary before 2017… if ever. Here’s hoping Mazda is able to keep this unique, distinctive drivetrain alive for future generations of enthusiast drivers.

    The rotary engine has been used in generators, snowmobiles, motorcycles, cars, trucks, airplanes and who knows what else. And it seems that as of today, only the Mazda RX-8 is still available with it wherein it sells in any quantity. Most car shoppers know nothing about it and couldn't care otherwise. It has always been an enthusiast's delight and has only really made its place in the world by powering light sports cars. And with the increasing sophistication of electronics, no doubt more strides can be made in better economy and fewer emissions. But this will be true across the spectrum of all I.C.E.'s, and since the rotary has similar operating and power characteristics to the two-stroke piston engine, maybe if Mazda decides to dump the Wankle but still needs an ace to attach to their name they could try to resurrect the public image of the good ol' "corn-popper". But this may not be as outlandish as it seems. Once ubiquitous in the small motorbike world, It is strange that the two-stroke was originally banned because of noise and smoke issues, but now it has made more than a comeback, and they are now far more common than ever, by their use in obscenely loud, powered lawn equipment and in the new kind of plasticky, puny putt-putt type of motorscooters. A few cars have used two-strokes in the past - most notably Saab and, more recently, the smoky, smelly, trashy Trabant - and so maybe if Mazda sends the Wankle out to pasture they could then pick up the mantle and tech-up the two-stroke for automotive use once again, in a new and higher calling, in keeping with the company's own somewhat romantic engineering ideal of doing something difficult just to do it, even when there is really little to be gained by doing so over standard procedures, much in the manner of the rotary. Whether any such new technology would be more expensive than continuing with the Wankle is the key issue; but they already tried to branch out not too long ago with the short-lived and seemingly unnecessary updating of the old Miller Cycle cylinder heads. Of course, if Mazda's nixing of the Wankle is done on purely economic grounds then any such argument is moot; but I too agree that the rotary has always been Mazda's 'hook', and if it were not for it and the Miata, just what would Mazda be, anyway. . . ?

    Have a nice send off party and decommission the Wankel. The only thing it has going for it is a power-to-weight advantage over piston engines, and that advantage is shrinking. Meanwhile, Mazda can ill afford to put development resources into a one-model low volume technological curiosity. Mazda is going to have enough trouble being competitive which the big boys and hasn't a person or Yen to spare on sentimental engineering projects. Back in the 1970s it was dedication to the Wankel engine and its low fuel economy, spotty reliability, emission control difficulties and high production costs that pushed Mazda into Ford's arms in the first place.

  • NJRide Now more than ever, the US needs a brand selling cheaper cars. I know the old adage that a "good used car" is the best affordable transportation, but there has to be someone willing to challenge the $45k average gas crossover or $60k electric one that has priced out many working and middle class people from the market. So I think Mitsu actually may be onto something. Call me crazy but I think if they came up with a decent sedan in the Civic space but maybe for $19-20k as opposed to $25 they might get some traction there's still some people who prefer a sedan.However, I just compared a Trailblazer on Edmunds to an Outlander Sport. Virtually same size, the Trailblazer has heated seats, keyless ignition and satellite radio and better fuel economy for almost same price as the Mitsu. Plus a fresher body and a normal dealer network. This has always been the challenge off brands have had. Mitsu probably would have to come in $2-3k less than the Chevy unless they can finance more readily to the subprime crowd.
  • MaintenanceCosts At least on the US West Coast, Waze is perfectly happy to send cut-through drivers down residential streets or to disregard peak-hour turn or travel restrictions. I hope if it's going to be standard equipment the company starts taking a more responsible approach.
  • MaintenanceCosts I'm more curious about the effect (if any) on battery lifetime than range. Drawing current faster creates more heat and if that heat is not promptly drawn away it could affect life of the cells.I agree this sort of thing can make sense as a one-time option but is consumer-hostile as a subscription.
  • Ajla "The upgrade is permanent" 🤔Journos really should be calling out the automakers like Mercedes that are attempting to make this sort of thing subscription only because it obviously doesn't need to be."with a one-time price tag of $1,195"This also shows the poor consumer "value" of Mercedes wanting $1200 per year for a 60hp jump on the EQE350.
  • Dukeisduke Will the next owner have to pay up, too, like with Tesla? What's the starting price of the Polestar 2? I saw a clean used one listed locally the other day, and it was under $50k. I wasn't sure if that was a deal or not.
